Safety Precautions
Detailed safety precautions:
Please read all safety precautions and operating instructions
before attempting to operate the unit. Keep all safety precautions and
operating instructions for future reference.
Water and moisture:
Condenser microphones are extremely moisture-sensitive. Never use
your microphone in close proximity to water (e.g. bath tubs, wash
basins, sinks, washing machines, pools, etc.).
Damage:
Take care not to drop your microphone as this can lead to severe
damage. JZ Microphones assumes no liability for any damage caused
by the user.
Service and care:
After each use, remove the microphone from its mount and wipe
the microphone down with a soft cloth and place it back into its
protective casing (included with the microphone).
Never open the microphone as it will void warranty!
Refer all servicing to qualifi ed and manufacturer`s appointed
personnel. Servicing is required when the microphone is damaged in
any way, such as liquid has been spilled or objects have been fallen
into the microphone, the microphone has been exposed to rain or
moisture, microphone does not operate normally or has been dropped.
Never remove grille covers in order to service microphone capsule.
The capsule system does not contain any user serviceable parts.
Usage:
Only use attachments or accessories specifi ed by the manufaturer.
Check if packing contains all of the items listed. If any of these
items are missing, contact your nearest JZ Microphones dealer or
JZ Microphones directly.
Always turn down the levels (means no sound) of the microphone
preamp or console while connecting or disconnecting the microphone
to avoid possible damage to your speakers or headphones and your
hearing.

BH Series Microphones Set Up
1. Firmly hold the wooden case and use your thumbs to open it.
(see pictures)
2. Replace the shipping screw from included shock-mount with the
included thumb screw. To unscrew the shipping screw use either
the included thumb screw or appropriate screw driver, or you can
use the coin if you have one with you. (see pictures)

3. Mount the shock-mount on the microphone stand. When it is
done, take your BH microphone, squeeze the shock-mount so it`s
both circular ends fi ts the two metal pins inside BH microphone and
accurately apply the microphone on the shock-mount and ensure
that microphone sits safe on the shock-mount (see pictures)
4. Included shock-mount gives you the opportunity to position and
angle your microphone to the sound source in many various ways
for desired results to be achieved (see pictures)
Tip: When using your BH series microphones on drum
overheads you can apply included shock-mount from the front
of the microphone.

BH Series Microphones Owners Manual
All BH series microphones come in a wooden case with included
FREE standard BH shock-mount and thumb screw for it to replace
a shock-mounts` shipping screw for easy adjustment when positioning
the microphone. This standard shock-mount fi ts to BH series micro-
phones only. Included shock-mount can be attached to any standard
microphone stand.
BH series packing includes:
1 x Wooden case
1 x BH series microphone
1 x standard shock-mount
1 x Thumb screw
1 x User Manual
1 x Warranty sheet
Installation:
Before mounting your shock-mount on a microphone stand replace
the shipping screw from the shock-mount with included thumb screw
for easy operation. Squeeze the shock-mount and carefully put on the
microphone.
There is removable adapter in your shock-mount which lets you mount
it on mic stands with either metric (Europe) or imperial-gauge threads
(North America). Make sure that your microphone is standing safe on
the shock-mount.
The angle of the microphone to the sound source infl uences the
sound of your recording; therefore, experiment with different
positions until you achieve the desired sound.
As all our microphones are extremely high quality, we recommend to
use a highest quality balanced XLR microphone cables in connection
with highest quality microphone preamps to grant cleanest signal path
from the sound source to your recording equipment.

The Golden Drop Capsule (GDC)
One of the most important components in every microphone is the capsule,
its design and how it transforms the reproduced sound in to electric energy,
giving a soul to your recording.
Golden Drop technology is Innovative capsules diaphragm sputtering
method, where a lot of tiny and different sized golden dots are systematically
sputtered on the capsules diaphragm. It is invention of Juris Zarins and is
applied to most of JZ Microphones products.
Advantages of Golden Drop technology
With applied Golden Drop technology, capsules diaphragm is lighter there-
fore it moves and gets to its default position faster than the same capsules
diaphragm without Golden Drop technology, imagine handling the truck
compared to sports car, in other words lighter diaphragm can detect and
deliver much faster changes in musical content.
It gives more clarity, precision, less colorations and distortions in frequency
response. When applied, Golden Drop technology can improve the sonic char-
acteristics of any type of ordinary capsule giving more realistic picture of your
recording.
BH Series microphones use 2 types of GDC
1. Single large diaphragm 27 mm GDC (GDC1)
GDC1 is single large diaphragm Golden Drop microphone capsule.
GDC1 is applied only to our fi xed cardioid BH2 and BH3 microphones.
2. Two separate and back to back placed large diaphragms 27mm
GDC (GDC2)
GDC2 is two separate and back to back placed single large diaphragm Golden
Drop microphone capsules combination.
Innovative GDC2 was developed for our fl agship BH series microphones to have
polar pattern options, where unwanted interaction between both diaphragms
is maximally reduced (due to air gap between the capsules) to have improved
polar pattern response, plus has all advantages from GDC diaphragm sputter-
ing technology to deliver the captured sound fi eld in more accurate way.
GDC2 is not working in cardioid polar pattern mode. Only frontal
capsule is working in cardioid mode.
GDC2 is applied only to our multi-pattern BH1s and BH1 microphones.

Electronics
All JZ Microphones products use Class A discrete electronics, where all
components are tested and measured for a maximum performance and
grants to the audio signal cleanest path and extremely low self noise
properties before any recording gear. All components are hand soldered by
our engineers to avoid overheating of selected parts. While soldering the
components, either it is done by un-experienced engineer or bad
programmed machine, overheating can ruin specifi cations of very carefully
selected electronic part.
BH series microphones are tube-less at this point, therefore electronic circuit
is designed to work perfectly without tube as modern electronics is developed
to manage the signal path without it.
BH series microphones are transformer-less, therefore electronics are de-
signed to have maximum performance with minimum self noise without the
transformer.
BH1s and BH3 series microphones comes with a PAD switch to have an option
to lower the signal level from -5dB to -20dB depending on microphone model.
Our PAD switch is applied to microphone electronics circuit right after the
capsule which avoids to cut low and high frequencies destroying the signal
quality, instead it just lovers the signal level allowing capsule to handle high
SPL`s and keeping the signal unaffected.
Important is that in most cases the microphone can handle high signal level
but the microphone preamplifi ers can`t. That is why we care about your pre-
amplifi er and made a BH1s and BH3 microphones with pad option.
BH series microphones share basically the same electronic parts. Every BH
series microphone except BH1s use component selection with tolerance 1.5 %
in differences between them (only 35% of 1000 parts can pass 1.5% tolerance
test)
Components selected for BH1s have tolerance 0.4 % and are custom-made
from those 1.5% parts therefore we are giving lifetime warranty for all BH1s
microphones.
Electronic circuit design and component selection for every JZ Microphones
product is done according to the capsule properties and its special needs to
grant the best possible performance and extremely low self noise before any
gear in the recording chain.
